BUMPER Post?..

Application filed. October 28, 1925. Serial N'o. 65,323.

, rl`hc invention relates to that type of bumper post. in. Which thebumper' head is supported by compressionmembers Which ex.- tendoutward', downward andV backvvard from thebumper headl to bearingson theroadbed, andI by tension members. Which extend downward, outward and.usually forward from-the bumper head topoints in advance thereof, Wherethey are secured to the roadbed'. In bumpers of this characterI theshock of lmpact is taken partly by the compression members as a downwardthrust., and partly by the tension members, Whicliresist..the lupwardpull. resulting from; the impact.. `The length ofthe base in bumpers ofthis sort.V varies consi derably,theanglesof the compression membersand. ofthe tension membersto the track plane being subject* to.alteration Within considerable range.r

`The. object of the present invention includes the distribution of. thecompression other bumper' structures..

and tension stresses, toa number of. different vties,. so as to. provideadequate anchoring.

structure substantially in. the track plane or above it,.thus avoiding,special suh-structures built into the roadbed',, and it also includesthe organization: and design 'of. the. several parts so'that they can beproduced' by simple and inexpensive' operations and quickly assembled onand connected. to* the roadbed. The invention. further includes thespecial means of attaching, the tension members, and alsootherfeatures5. Which Will. appear below vand.

In the particular embodiment of the invent-ion villustrat-ed' in thevdrav fings.the bumper head l is provided at eachV side, withdownwardly, outuf'ardly and rearwardlyfiextending portions 2,' (Fig. 3)Which in the presentl instance are shaped to fit channel' 'irons.consisting. the compressionv members' e. The opposite ends ofthecompression members abut against the shoulders 4 on the bumper head andon similar lugsor shoulders l@on the compressiontrack fixtures. 5 whichlatter are located opposite each 'other porting ties. 'Thecompression`fixtures are connected bv cross tie-rod 8 Which ispreferablyconstructed as indicatedin Fig. .11'

with an upset head 9 at each end, the intermediate portion vbeing.adapted for insertion laterally into corresponding aligned slots 1.0 inthe compressicn fixtures before these are separated their full assembleddistance, and the heads 9 being adapted to be received respectively inundercut recesses'll' (Figs. 1 and ll) at the outerend of each slotlOWhen the fixtures are moved apartt the full assembled distance requiredfor placing them on-the gitudinal. anchor bars 11 eachprovided atits iboth of the arrangements illustrated they an extending transverselyofthe trac a j In the illustrated bumper post the bumper jhead 1 isprovided with tension member seats 14 (Fig. 3), vin the form of channelshaving adjacent flanges 15 and which extend outward, vdownward andforward from the center where there is central a slot extending downwardand forward through the bumper head. This slot and the channels are forthe reception of the upper bent ends 17 of the tension bars 16, whichbars are bent in their own longitudinal plane with a curvatureconforming to the bottoms of the channels, 14:,

and Vwhen placed in the channels the correspondings ends 18 of: the twotension bars project below the head wherel they are secured together andto the head by a pin 19. provided with cotter pins as shown. Thetensionbars extend downward, outwardand forward, and

are bent in their own plane, at their lower and'forward ends, so as topass completely under each Vrail in the form of a hook. The pull ofthese tension members is sustained by tension track fixtures 20 locatedopposite each otherin'the track and each of which seats on two adjacentties adjacent the base of the f rail, andon the outside of the rail web,the

fixture being spiked to the tiesa-nd secured to the web by bolts 6. Itsmovement endwise of the rails isfurther obstructed by the shoulder 21which abuts against the front of the adaccnt tie. The tension fixturehas a body portion beneath the rail and between adjacent sol i centties.

ties and which provides a bearing 22 to engage the rail, and beneath therail and saidV bearing, aseat 23 for the tension member. There arespecial advantages in this relative arrangement of said bearing andseat, and it is preferred. By virtue of it tension'produced by impact onthe bumper head is transmitted to the track fixtures as compression, thepart ofthe 'track fixtures subjected there- Vto beingadequatelysupported by the rail on the underside of whose base it bears.Furthermore the track fixture, when located as illustrated and spanningthe space between adjacentties and spiked to each outside the rail,vtakes up as downward thrust part of the force to be dissipatechthe partof each tension fixture extended outward from the rail resisting anytendency to turn the rail up and out about the'outer edge of its base,and any tendency to bow or bulge downward the part of the Vfixturebetween the seats on the adja- The seat 23 is formed as a channel'exstending from the inside of the rail to the outside of the rail'where it terninates in a slot 211 passing up through the fixture. Theangle andtcurvature of the channel are such as to adapt it to receivethe adjacent end 25 of the tension bar 16`bent outward and upward intohook form, preferably on a curve of the fixture and with lthe fixture tothe web of the rail, by bolt 26 which passes therethrough. The fullcross section of the tension members is thus maintained throughoutexcept near the extreme ends where the holes for the pin 19 and thebolts 26 are located, so that the parts subjected to maximum strain arenot weakened in any way.

`The two tension track fixtures are connected'and spacedby a pipe 27,each end of which fits 'overan inwardly projecting cylindrical lugv 28formed on the fixture ini'ear of the tension bar channels 28. Each ofthese track fixtures andthe adjacent end of the cross bar are thusprovidedwith socket and seat portions permitting the fixtures and' crossbar to be "assembled by movement toward each other crosswise 'of thetrack, and

preventing their separation after they are fixed in assembled position.In order to divide the pullofthe tension members among various adjacentties, four as shown here, and as in the case of the Vcompressionmembers, additional anchor bars 11' identical in function with theanchor bars llalready described but differing therefrom slightly inconstruction are employed. These bars 11', which seat on the tie underthe track fixture have their rear ends formed Vinto hooks or knuckles12' hooked into a recess 13' in the tension track fixture. The fiXtureis formed with a bottom recess 29 and the rear end of the anchor bar isconfined in this recess when the fixture is spiked to the tie and isthereby` prevented from getting loose onl the recoil.

after the bumping post has sustained va shock.

A hood 30 'covering the extended end of the anchor bar recessl and thehook 12' guards against accidental dislodgment of they hook. The tensiontrack fixtures and the connecting` cross bar constitute tension trackifixture structure seating under the respective rails and to which thetension members are connected adjacent the rails.

It will be observed thattheinvention avoids the use of rails bent andtwisted in different planes as heretofore commonly employed, the

re-shaping of such rails to their originalform V i vafter distortion, asthe result of displacement from collision, being beyond the skill of theusual track hand, whereas the simple'tension or ties.

bars bent each only in its own plane can be readily restored to, theiroriginal shape by theordinary track gano; It will be noted also thateach track fixture isformed of a base` portion to engage the ties-and anupriglit wall ,portion to engage the rail Web. By making this wall of'abo-ut theheight indicated, it will serve to. form an adequateattachment to various sizes of rails, thus making the bumper structureas a whole adapted to any of the common sizes of railway tracks.
